DEMQUN TABLE RIM.

Application filed March 2, 1914. Serial No. 822,007.

T all 1132mm it may concern."

Be it known that I,'JosEri-I B. ARTHUR, a citizen of the United States, residing at Hutchinson, i-n the county of Reno and State of Kansas, have invented certain new and useful Improvements in Demountable Rims; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in demountable rims for use especially in con nection with automobile wheels and the primary object of the same is to provide an extremely simple, strong, and durable device of this character which may be quickly and easily attached or detached.

A secondary. object is to construct the rim and its co-acting parts in such a manner as to allow said rim to be readily removed with the necessity of but one mechanical movement.

Still another object is to construct the rim in such a manner as to. render standard, quick detachable and clencher tires readily applicable thereto and removable therefrom without the necessity of first removing the rim.

lVith the above objects .in view the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein Figure 1 is a side elevation of an automobile wheel showing the application of my improved demountable rim thereto, the rim being secured'iu position; Fig. 2 is a similar view of a portion of a wheel showing the parts in the position which they assumewhen detaching the rim; Fig. 3 is a transverse section on the line 3-3 of Fig. 1; Flg.

4 is a. similar view on the line' l4 thereof;-

and Fig. 5 is a detail vertical section through a portion of the folly and rim and showing more particularly theoperating mechanism for expanding and contracting the clamping or wedging band to be described.

In the accompanying drawings, I have shown my improved dcmountablerim as applied to an automobile wheel W which comprises the usual hub ll, spokes S and ifelly F. The periphery of the telly F is provided with a felly band 1 whicn is wedge-shaped in cross section (see Figs. 3 and l) and is secured in position upon said telly by means of bolts 2 which pass through said band and said telly and receive nuts 3 on their inner ends. By reference to Figs. 3 and 4, it

its outer face only, while its inner face lies parallel to the axis of the wheel lV. Thus it will be seen that by slight alterations, to be hereinafter described, the wedge-shaped will be seen that the band 1 istapered upon bands 1, may be applied to automobile wheels of usual construction.

The outer edge or the folly F is provided with an annular groove or recess 4 in which is rigidly secured a wedging ring 5 which, as shown, is tapered on its inner side as shown at 6, said tapered portion extending from the outer edge of said ring inwardly to a suitable point and containing through out the circumference of the ring 5. The outer face of the felly F is further recessed as at 7 for a purpose to appear, said recess extending throughout the circumference of said folly and terminating at its opposite ends in an enlarged recess 8 in which the operating mechanism to be described is located.

The rim 9 is here shown as formed upon its periphery, with an annular bead or flange 10 on its inner edge, while its outer edge isprovided with a continuous groove 11, said flange and groove being adapted for co-action with the usual tire clamping rings (not shown). The inner side of the rim 9 is provided at its central portion with an integral wedging hand ,12 which, as clearly shown in Figs. 3 and l, is beveled on its inner side and co-acts with the beveled portion of the telly band 1, said band 12 and the rim 5) being secured in position in a manner to appear. As clearly shown in the drawings, the band 12 terminates a suitable distance from the inner and outer edges of the rim 9 and said rim is provided on its outer edge with an inwardly extending" bead 13 which extends throughout the circumf rence of said run.

Slidably mounted. between the head 13 and the outer edge of the wedge band 12 is a clamping or wedging ring l lwhich, a clearly shown in lugs. t and 5, is beveled on its outer side as at 15 for co-action with the beveled portion 6 of the ring 5. The 0pposite ends of the ring 14 are pro idc-id with oppositely thremilcd extensions it which are engaged with internally threaded sockets formed in the opp ends oi" a turn lJllClilG 17 which redu .d at its con;- tral portion and. provided. with a plurality of worm teeth 18 with which a laterally extending worm l9 meshes. The Worm 19 is revolubly mounted in suitable yoke 20 which extends inwardly through the recess 8 and is provided with a polygonal opening 21 for the reception of a suitable tool by which it may be rotated.

For the sake of preventing the rim 9 from creeping upon the telly band 1, ll provide the wedgiug band with inwardly extending! studs 22 which are adapted to engage notches 23 formed in tl e outer edge of said band. The W dging ring 5 is prov ed with notches 24 through which said lugs 2&3 may freely pass when the rim is being removed or applied in a manner to appear.

When the rim is in ,position upon the wheel, the tapered inner side of the wedging telly band 12 is in contact with the tapered outer face of the telly band 1 and the clamping or wedging ring let is contracted by means of the turn buckle 17, to cause its tapered outer side 15 to contact with the tapered inner side 6 of the ring: 5 and thereby draw the tapered faces of the elen'ients 1 and'lZ into binding contact, When the ring: M stands in this position, its inner will be forced into the space 7, whileits outer edge will move inwardly within the space; between the outer edge of the band 12 and the bead Thus it will be seen that the rim 9 is rigidly secured in position upon the wheel. When, however, it becomes necessary to remove the rim, a suitable tool may be inserted in the opening 21 and the worm 19 may thereby be rotated in such a direction as to force the meeting ends of the Wedging ring 14 outwardly and thereby expand said ring to a suilicient extent to allow it to pass freely fo er the outer edge of the ring 5, whereuoon the entire iiui may be removed. If no sl'iould become necessary to remove wedgmgg ring; from the rim 9, it c e V to rotate the w in proper direction to draw the en ring tQjGtbGi 'ul'Ml thus eontrac' whereupon, it may be readily disen aged,

From the herein described COHSJEUGtlOiL it will be cleail.

seentljiat have produ- JL i'very simple, yet efticient demountable which designed primarily for use in tion with automobile wheels and 1 ch standard. tires may be employed.

further seen that the tires he from the rims v first removing f -n important feature of the m it adaptsthe riuti for use cit-l l mountable rim or as a rigid rim.

From the foregohg descriptiom taken in connection with the comganying drawings, the construction and operation of the invention will bereadily understood without reouiring a more extenilml explanation.

Although, I have described my invention with considerable i'ninuteness, 1 do not wish tinu the on periphery of said folly and having a beveled outer periphery and a rim applied to said :lelly hand, the inner periphery cl said rim being beveled coincident to the inclination ot the outer periphery of said band; of a ring removably secured in the oilportion of said telly, the inner face of a portion of said ring being beveled and spaced from portions of the rim and telly band, a split rin-g disposed in the space be tween the beveled portions of the aforesaid ring and the zhiljtiCOIll? oi the rim and telly band, "the outer face of said split ring being beveled coincident to the beueling of the. portion of the first mentioned. ring, itnd means for contra.- 1% ea d ring in the space in. which the same i l s seated whereby to causethe rim to bind tightly on the folly band and remain secured. in position.
